Description

This article introduces the electronic component model 74HC02MX, which belongs to the product category of gates and inverters. This model utilizes advanced silicon-gate CMOS technology and achieves operating speeds similar to LS-TTL gates with the low power consumption of standard CMOS integrated circuits. All gates have buffered outputs, providing high noise immunity, and the ability to drive 10 LS-TTL loads. The 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.
